Design Principles

  • Security First

    Capability-based access control ensures only authorized operations succeed

  • Performance

    Asynchronous I/O allows non-blocking operations and concurrent request handling

  • Modularity

    Clean layer separation with well-defined interfaces between components

  • Reliability

    Comprehensive error handling and graceful degradation paths

๐Ÿ‰ Meet Rory the Ouroboros

Rory the Ouroboros

Rory is the beloved mascot of Futura OS โ€” a self-contained serpent that feeds back into itself, eternally consuming and renewing. With pastel coloring and circuit-board patterns woven throughout her form, Rory embodies the kernel's capability-based design philosophy.

Like the ancient ouroboros symbol from mythology, Rory represents the eternal cycle of system evolution and self-improvement. She's a reminder that the best systems are those that can learn from themselves, improve their own foundations, and grow stronger with each iteration.

  • Self-Containment โ€” Rory reminds us that a well-designed system is self-complete and harmonious
  • Continuous Evolution โ€” Like her endless consumption and renewal, Futura continues to improve
  • Capability-Based Security โ€” Rory's circuit patterns represent the fine-grained access controls at Futura's core
  • Elegant Design โ€” Her pastel aesthetic reflects the beauty of well-crafted systems
